[one-users] Problem starting VM over a SSH system datastore

Hello Ruben,
Ok, I understand it. However, why the logs show this line first:
[...]clone
gpodmc.smos.lan:/var/lib/one//datastores/1/91209cfc6a24a39e60b42d9cd6ae5d7f
dpgsrcorepfw-3.smos.lan:/datastore/109/8/disk.0 8 1
(that I think it is perfectly aligned with your explanation)
and later it really tries this:
cp /datastore/1/91209cfc6a24a39e60b42d9cd6ae5d7f /datastore/109/8/disk.0
Why using /datastore in the source of the copy instead of
/var/lib/one/datastores?
Cheers
Fernando

datastore
When the images are registered (oneimage create) they are placed (in
filesystem-based datastores) in
$DATASTORE_BASE_PATH/<ds_id>
DATASTORE_BASE_PATH is either from oned.conf or from datastore template
(BASE_PATH attribute).
This images are then copied in the hosts to
$DATASTORE_LOCATION/<ds_id>/<vm_id>/
Note that those are different paths (one for the front-end) and the other
for the hosts.
If you want to access the default location, there is no need to set
neither DATASTORE_BASE_PATH nor DATASTORE_LOCATION.
Cheers
Ruben

Hello everyone,
I'm deploying my first cloud with ONE 4.4 and I'm facing a problem that I
don't understand. I have read all the related guides and I though I had
understand them but obviously it's not the case.
My problem is that after creating a SSH System datastore to just copy the
VM images from the frontend to the hosts, every time I try to start a
virtual machine I end up with the following error messages in the log:

The DATASTORE_LOCATION is pointing to "/datastore"
This is the output of the "onedatastore show" command:
=========================================================================================
[oneadmin at gpodmc one]$ onedatastore show 109

What I really dont't understand is why ONE is trying to access the source
image from
/datastore/1/91209cfc6a24a39e60b42d9cd6ae5d7f /datastore/109/8/disk.0
instead of using
/var/lib/one/datastores/1/91209cfc6a24a39e60b42d9cd6ae5d7f
/datastore/109/8/disk.0
?
Any body could explain to me what I'm doing wrong, please?
Regards
Fernando
